Abstract

A total of 472 field-collected Ixodes ricinus ticks from southern Germany were investigated by immunofluorescence for the presence of Borrelia burgdorferi with a polyvalent rabbit immune serum and with monoclonal antibodies specific for outer surface proteins A and C (OspA and OspC, respectively). Borreliae were detected in 90 ticks with the polyvalent immunofluorescence assay. Infection rates in adults (females, 20.2%; males, 25.2%) were significantly higher than in nymphs (12.1%). OspA was detected in 77 ticks and OspC was detected in only 1 tick with the respective monoclonal antibodies. We therefore conclude that B. burgdorferi in unfed I. ricinus ticks usually expresses OspA and very rarely OspC.

摘要

利用多价兔免疫血清以及分别针对外表面蛋白A和C(分别为OspA和OspC)的单克隆抗体,通过免疫荧光法对从德国南部野外采集的472只蓖麻硬蜱进行了调查,以检测伯氏疏螺旋体的存在情况。通过多价免疫荧光检测法在90只蜱中检测到了伯氏疏螺旋体。成虫(雌性为20.2%;雄性为25.2%)的感染率显著高于若虫(12.1%)。利用相应的单克隆抗体,在77只蜱中检测到了OspA,仅在1只蜱中检测到了OspC。因此,我们得出结论,未进食的蓖麻硬蜱中的伯氏疏螺旋体通常表达OspA,很少表达OspC。
